- Support of Win8.1
- Significantly improved file data cache. It makes reading/writing of files faster (minimizes the callbacks calls by composing several read/write requests into one).
- GPT partitioning support for fixed disks. Allows to correctly show greater than 2Tb disks.
- File "valid data length" support (added an optional callback for it).
- Allows to create a virtual storage, which is "absolutely" the same to physical one. It helps to use some Windows features that only work with physical storages. Such as automatically recreating network shares on a virtual disk after the system reboot.
- Some other features on which we are still working.

Happy dance!
Awesome. :)

Hopefully, we are also getting an increase in the write cache buffer size.
Since the virtual storage disk must have a disk policy of removal, it does not take advantage of the Windows buffer cache.

GPT partitioning is present in CBFS5 and CBFS uses it in the case virtual disk is PnP and "fixed" (i.e. StorageType is stDiskPnP and StorageCharacteristics is 0). This is done so because for non-Pnp disks there is no any MBR/GPT at all, and for removable disks Windows doesn't support GPT.
